An automated bidding system where a bidder may enter a maximum price and the
auction system will increase his/her bid as necessary until the maximum is
reached.

For example, Bidder A is the first bidder on an item whose starting bid is 1.
He/She places a maximum bid of 10, which the system holds in confidence until
needed. The system places his/her initial bid. Bidder B places a maximum bid of
8. The system automatically bids for Bidder A and Bidder B until Bidder B's
maximum bid (8) is surpassed. Since Bidder A's maximum bid is higher than Bidder
B's, he/she remains the high bidder.
